My car alarm is soft sounded and my car wont start, please help immediately as my car is stuck at someone's?

Hello all. This may be a long story but it must be explained. First off, I started my car and it sounded fine so I drove my car off to an interview. After the interview, I started my car and it sounded fine again...then, I drove down the street and the car just died on me when I came to a complete stop and accelerated it. So my car was in the middle of the road, I had to push it to the closest place possible which was the bank. Then, I looked at my gauge and there was gas in there, and everything else is fine besides the anti-freeze light that's on. I opened my hood and there was still 25% left of anti-freeze. I tried starting my car multiple times and still it doesn't work. I called my uncle, he came and tried to start it but couldn't and said I may need gas so we pushed the car to the gas station and i pumped $10 then the car started. I drove on the way home which was 15 minutes away on streets and decide to visit a friend to tell about my experience as I park the car outside his house. About 15 minutes later, I went to the car and pressed my alarm button so i can access my car without it setting off (alarm has been working fine until now...), I hear that my alarm button didn't trigger a signal for me to open the door so I pressed it a few times then opened the door and I hear my alarm go off but it was a really soft sound. I then thought it was another problem :(. I started my car then try to drive off and it died on me again (drove off 5 feet). I try starting the car but it sounds like it's choking and my alarm still go off but you can barely hear it. Battery seems to light everything on, headlights and all and I have gas, the drive wasn't too far from the interview to home and friend's house. I went to my friend's house day after day to start it and still nothing..but yesterday, it seems like the car almost started but didn't. I don't know what the problem is, please help me....I forgot to mention I have a 1994 Mercedes Benz C220. Please help me, Because of this car failure, I had to call quits on the job. I have no one to provide me a ride to work and I have no money for tow. I would appreciate the help and God Bless You All.
